ROLL-PAPER HOLDER AND CUTTER.

SPECIFICATION forming part of Letters Patent No. 398,7 50, dated February 26, 1889. Application filed July 23, 1888. Serial No. 280,758. (No inodelfl To @ZZ whom it may concern.-

Be it known that l, ABBOTT Q. Ross, a citizen of the United States, residing at Cincinnati, Hamilton county, Ohio, have invented new and useful Improvements in Roll-Papcr 1 Holders and Cutters, of which the following is a speciication. i

My invention relates to that class of rollpaper holders embodying, in combination with the paper roll, a heating or gravity friction-bar whose function is to retard the rotative momentum of the roll in withdrawing the paper web preparatory to tearing oft' a desired portion.

An example of the type or class of holders to which my invention is applied is shown in a former application pending herewith, upon which my present invention is in the nature of an improvement. In said other application is shown a floating bar resting by gravity upon the periphery of the roll and upon the free end of the web without adjuncts, and having its front beveled to constitute a tearingknife.

In my present invention I employ a floating bar guided asin said former application, but provided with a proj ecting strip of metal constituting a tearing-knife, and with a pivoted drag-bar. The floating bar in this case rests upon the roll beneath the paper strip, the latter passing out over the friction-bar and under the tearing-knife, one of the principal objects of the construction being to cause the free end of the web, after severance of a portion of the same, to remain in such convenient relation to the knife and the paper roll as to facilitate a renewed grasp and avoid the necessity of turning the roll independently to project a new margin for such new grasp.

Mechanism embodying my invention is eX- hibited in the accompanying drawings, in which- Figure l is a general perspective view of the device completed; Fig. L", a vertical cross-section of the same, and Fig. 3 a detail showing the connection of the floating bar and the tearing-knife.

Referring now to the drawings, A designates the paper roll; B B, the side standards in which the same is journaled, and C a floating bar guided by its end projections, c C, in the vertical slots of the standards. The bar C is flat, and rests one of its flat sides upon the periphery of the roll and follows the same downward by gravity as the roll diminishes in size. Secured across the top of the bar C upon elevated projections d, near each end, is the tearing-knife or straight-edge D, space enough being left between itself and the knife and horizontally between the projections ct to allow the passage of the free end of the paper strip outward from the roll beneath the projecting straight-edge. I also arrange a bail-like drag-bar, E, which may be formed of wire pivotalljf'bent, engaging b vits end in the guide projections c at each side and pas ing either outside or inside of the standards.

The function of the drag-bar is to rest upon the roll behind the iioating bar C to prevent the free endof the web or strip from being displaced by any accident.

The operation is as follows: The free end of the paper strip or web w is passed out under the drag-bar E, over t-he Heating-bar C, and under the knife D, as shown. The paper is thus perfectly guided between the projections ct, and is torn by an upward pull against the knife. The projection of theknife above and in tangential relations to the roll A leaves a considerable vertical interval between the surface of the roll and the outer edge of the knife, and in this space the free end of the unsevered portion partly falls by gravity, as

indicated, and remains in convenient position to be regrasped. The drag-bar behind prevents this free end from receding, and the parts thus remain in position for convenient use, and the rotation of the paper roll to project anew a grasping-margin of the strip Aor web is thus rendered unnecessary.

The ordinary act-ion and function of the frictioirbar in retarding the revolution of the roll and preventing the overrunning of the web are similar to that of any similarly-mounted frictionbar, and need not be here described.

I do not claim herein, broadly, a fioating weighted bar adapted to be held by gravity alone against the periphery of a roll of paper and having a cutting edge or knife removed from the point of contact between said bar IOO and roll, as such matter is made the subject ot' claim in another case iiied by me .lul y 3l, 1888, Serial No. 281,580. l

I claim as my invention and desire to Secure by Letters Patent of the United States- In a paper-roll holder of the character described, the Combination, with the standards and their guides, ot the frietion-bar bearing direetlyon the roll of paper, and the tearing'- knife Supported on Said Frietion-l'iar, but projecting in a pla-ue above the same, so as to leave a clear space between the Vtwo and permit the web of papelito pase over the `frictionbar and under the tearing knife, whereby
